Cyrrus releases Safeguarding Guide

Today Cyrrus released our new Safeguarding Guide, exploring the various services Cyrrus provide to address physical and technical safeguarding issues. Cyrrus can help ensure the safety and efficiency of air operations in and around airports, by identification, assessment and mitigation recommendations for new and existing developments.  Cyrrus employ a tried and tested approach to address the critical areas of:

  • Physical safeguarding of the Obstacle Limitation Surface (OLS) in and around the airfield, to monitor and mitigate development;
  • Physical safeguarding of the Instrument Flight Procedures that have their own unique set of surfaces separate to the OLS;
  • Technical safeguarding to protect an airports Communications, Navigation and Surveillance facilities from interference or disruption by development.

Cyrrus supports Gatwick Airport’s environmental policy

As part of the CAA’s Post Implementation Review of the RNAV-1 SIDs at Gatwick Airport (CAP 1346) it was noted that the new RNAV SIDs did not achieve adequate replication of the existing conventional SIDs on Route 4.  This particular departure presented unique challenges due its wraparound nature and requirement to follow the existing NPR. Cyrrus designers were able to use innovative development coupled with manipulation of ARINC Path-Terminators to design a new RNAV SID that provides a degree of track dispersion whilst remaining within the NPR in normal meteorological conditions.

More information can be found on the Gatwick Airport website:

Human Factors Assessment

Human Factors (HF) study the relationship between humans and the equipment, system or facilities they interact with. Operational safety, efficiency and productivity can all be improved if HF are considered holistically during the requirements definition, design, procurement and transition lifecycle phases of projects. This is essential in an aviation environment where safety-critical systems are in operation.  Following delivery of new systems and processes, the regular review of HF assessment and changes ensure continued safe and efficient operation.

Cyrrus has significant experience of conducting HF assessment of both new and existing equipment, systems and facilities.  Our tasks follow a formal, tried and tested process based on the guidance provided by EUROCONTROL (Human Factors Case). The process systematically identifies HF issues that could arise during the implementation of new equipment, system or facilities and identifies and reviews potential mitigation. The main areas of study within our HF assessment includes the working environment, the interacting organisation and staffing, training and development, procedures, roles and responsibilities, teams and communication, and the human in the system.

This process can be equally applied to both new and legacy systems, equipment and processes, so please contact us and see how Cyrrus can assist you.

Air Navigation Service Provision

The environment for the supply of Air Navigation Services (ANS) to airports in the UK has undergone a marked change over recent years. The introduction of competition in Terminal Air Navigation Services has resulted in the achievement of operational cost efficiencies for many airport operators.

Fundamental to the selection of this key service provider is a robust, transparent, traceable and effective procurement process. One which captures the airport’s operational requirements within clear and precise procurement documentation design.

To meet this need Cyrrus, along with our partner Northstar, developed an OJEU Compliant Procurement Process which is unique in its application in the UK. The process has been refined and enhanced over five separate procurement cycles to a point where the process is capable of being executed stand alone, or integrated within client procurement process, aligned as required to airport governance and project controls.

With over five years’ experience in running this process for our clients, we have received laudable praise from both airports we have assisted and the ANS providers involved, for the clarity of process, concise requirements and the performance of the tendering process.

We can tailor and deploy our process and expertise rapidly to meet client requirements worldwide and can provide valuable insight into the competitive and supplier transition process. Contact us now to find out how we can help drive operational cost efficiencies in this vital area of your airport operation.

Another Contract Award Win for Cyrrus

Cyrrus is delighted to have been selected for an upcoming project at Doncaster Sheffield Airport. The team will undertake the airspace change for the introduction of satellite-based aRea Navigation (RNAV) Standard Instrument Departures (SIDs) at the Airport with work commencing imminently.

The Gamston VOR will be withdrawn by NATS as part of the National VOR rationalisation programme, which is approved by the CAA. Due to this change in the navigation infrastructure, the existing conventional SIDs at Doncaster Sheffield Airport will need to be changed to RNAV SIDs. In addition, the Airport has decided to introduce new RNAV GNSS Instrument Approach Procedures (IAPs) to compliment the RNAV Departures.

The introduction of the new RNAV (GNSS) SIDs and the IAPs form part of a compliance project with the CAAs Future Airspace Strategy (FAS) and policies for the implementation of Performance-Based Navigation (PBN) in the UK.

Speaking about the project, Rob Cooke, Operations Director at Doncaster Sheffield said;

It was clear from our competition tender process that Cyrrus provided the most professional and cost-effective solution to the RFP bounded by a realistic delivery programme. We look forward to working with the Cyrrus Team to deliver a successful outcome to this project.”

Cyrrus is proud to assist Doncaster Sheffield Airport with this development to ensure that it can meet its business continuity needs and accord with FAS requirements. Please contact us to see how Cyrrus can help with any airspace requirements you may have.

Keeping up-to-date on Consultation Industry Best Practice

Principal ATM Consultant at Cyrrus, Richard O’Gorman, undertook a course at The Consultation Institute in London. The Consultation Institute is recognised and highly thought of worldwide and specialises in offering advice and guidance across the world of public consultation and engagement, aiming to support those undertaking challenging projects. With the advent of the new CAP725 on the horizon, which advocates greater transparency and places more focus on pre-consultation, it is critical that change sponsors fully understand what is emerging as the expected benchmark when it comes to consulting on change. The critical stage of pre-consultation is becoming increasingly important and is fraught with potential pitfalls. As Cyrrus prepares itself for more open and expansive consultations, it is now well placed having embraced the latest thinking on industry best practice.
